Schelinger A03-V7-4-40-030 Residual Current Circuit Breaker 4P 40A 30mA AC Type

The Schelinger A03-V7-4-40-030 is a high-quality 4-pole residual current circuit breaker (RCCB) engineered to provide essential electrical safety in AC circuits. This device is designed to monitor electrical currents and automatically disconnect the circuit if a leakage current is detected, thereby protecting users from the risk of electric shock and preventing potential fire hazards caused by insulation faults.

Advantages

This residual current circuit breaker offers robust protection for both residential and commercial electrical systems. Its 4-pole configuration allows for versatile installation in three-phase electrical networks, ensuring comprehensive coverage for various appliances and circuits. The device is built to high standards, providing reliable performance and long-term durability in demanding electrical environments. By integrating this component into your distribution board, you significantly enhance the safety profile of your electrical installation.

Suitable for

• Residential electrical distribution boards
• Commercial building electrical systems
• Protection of lighting and power circuits
• General AC electrical installations requiring leakage current protection

This device is not suitable for DC-only circuits or systems where high-frequency leakage currents are present, as it is specifically designed for AC type applications. It should not be used as a primary overload or short-circuit protection device, as it is intended solely for residual current detection.

Key specifications

• Number of poles: 4
• Rated current: 40A
• Sensitivity (rated residual operating current): 30mA
• Type: AC

Installation of the Schelinger residual current circuit breaker should be performed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within a distribution cabinet. Ensure that the supply voltage matches the device specifications before connection. Once installed, the device should be tested using the integrated test button to verify its operational integrity.

What to consider before purchase

• Verify that the 40A rated current is sufficient for your circuit load
• Ensure the 30mA sensitivity meets the safety requirements for your specific application
• Confirm that your electrical system is compatible with AC type residual current devices
• Check available space on the DIN rail within your distribution board

Regularly test the residual current circuit breaker using the built-in test button at least every six months to ensure the mechanical and electrical components remain functional and responsive to leakage currents.
